A Python-to-Vim bridge decorator that allows transparent calls to Python functions in native Vim scripts.
Project description
What is it?
vim_bridge is a Python-to-Vim bridge decorator that allows transparent calls to Python functions in native Vim scripts.
Installation
Simply install the vim_bridge Python package, using setuptools, easy_install, or pip.
Usage
In a Vim script, decorate your Python functions as follows to expose them as native Vim callables. Both arguments and return values are casted so it should be transparent:
python << endpython from vim_bridge import bridged @bridged('first', 'last') def SayHello(first, last): return "Hello, %s %s!" % (first, last) endpython " Now call directly into the Python function! echo SayHello("John", "Doe") " prints "Hello, John Doe!"
Supported
The following data types have proven to work:
Strings
Integers
Lists
Exceptions
More examples
Passing in a list:
python << endpython from vim_bridge import bridged @bridged('list') def GetLongest(list): return max(map(lambda s: len(s), list)) endpython echo GetLongest(['one', 'two', 'three', 'four']) " returns 5 (because "three" is 5 chars long)
Catching exceptions:
python << endpython from vim_bridge import bridged @bridged() def WillCauseException(): raise Exception("Oops") endpython " This will throw an error to the user... echo WillCauseException() " But here's how you can catch that in Vim try echo WillCauseException() catch echo "Something went wrong. Aborting." finally echo "Cleaning up." endtry
Using Python stdlib functions to do work that would be more difficult using pure Vim scripting:
python << END import os.path from vim_bridge import bridged @bridged('path') def NormalizePath(path): return os.path.realpath(path) END echo NormalizePath("/this/../or/./.././that/is/./a/.//very/../obscure/..//././long/./../path/name") echo NormalizePath("..")
